The Pandora Engraving Craze: Is the Viral Personalized Necklace Worth the Hype?

To evaluate whether a customized Pandora necklace will survive a decade in a jewelry box, look at the underlying metallurgy. Pandora relies primarily on two metal formulations for its personalized lineup: standard 925 sterling silver and a proprietary copper-silver core finished with a 14k gold plating.

Sterling silver contains 92.5% pure silver and 7.5% copper. Copper provides tensile strength, but it oxidizes readily when exposed to airborne sulfur compounds, skin acidity, and moisture. Real-world tarnish resistance depends on how often the piece is polished and sealed. On an engravable heart tag, tarnish settles first inside the micro-crevices left by the laser. While light oxidation can make black text stand out more clearly, uncontrolled tarnishing muddies intricate script fonts until the letters bleed together.

For gold-plated pieces, the structural stakes are higher. The laser must vaporize enough material to leave a distinct visual trace without burning clean through the thin gold flash into the base alloy below. If the laser cuts too deep, it exposes the copper-heavy core to air, triggering localized green discoloration around the letters within months.
